Patent DE-3314306-A1 (DE)
Title: Sealing pipe-connecting plug-in system
Inventor: MAYER HERBERT
IPC: F16L37/092
Filed: 1983-04-20
Abstract: The invention relates to a sealing pipe-connecting plug-in system for fluid or gaseous media. Said invention creates a plug-in, force-fitting, sealed pipe connection which considerably reduces manual influences on sealing and torsional stress, and is able to absorb thermal expansion of the pipe. This is achieved according to the invention in that the pipe end, which is provided with a securing sleeve and a latched-in, sprung ring in a specially shaped groove, is pushed into the connecting part, which is equipped with a seal, until the ring is held in the hole and the claws of the securing sleeve snap into the depressions of the connecting part. By means of its collar, the securing sleeve, which is thus inverted and locked over the connecting part, prevents the ring sliding out of the connecting part and presses it out of the conical groove in the event of an axial tension load, it being wedged between the pipe and the connecting part hole and preventing the connection being released. Figure 1 shows an exemplary embodiment. The advantages are in the saving of energy, aids, compensators and assembly and test time. <IMAGE>

Title: Method and device for ultrasonic scanning of an object by means of an ultrasonic head
Inventor: HASSLER DIETRICH DIPL ING
IPC: G01S7/52
Filed: 1984-03-12
Abstract: In this method, an ultrasonic head is used which exhibits a multiplicity of adjacently located ultrasonic transducer elements (2). During the reception along a straight-line scanning line (Z1), different numbers of the ultrasonic transducer elements (2) are successively activated and thus adjusted for reception from different depth ranges ( DELTA t1,  DELTA t2,  DELTA t3). The aperture (A1, A2, A3) is increased step by step. The centroid of the aperture travels in the scanning direction over the ultrasonic transducer elements, one corner point remaining fixed. During the travelling, the directional characteristic of the respective active aperture (A1, A2, A3) is set in such a manner that a zig-zag-shaped scanning curve (Z'1) is obtained which largely approximates the straight-line scanning line (Z1). During the scanning of the greatest scanning depth of the object, all ultrasonic transducer elements (21 to 2N) are activated in this method. The device for carrying out the method contains for each element (2) a channel which comprises a depth compensation amplifier (10), a controlled switching device (12) and a delay device (16, 18), the outputs of these channels being connected to a summing element (22). <IMAGE>

Title: Auxiliary device for use when changing shaft seal parts
Inventor: JENSEN NIELS DUE
IPC: F16J15/00
Filed: 1984-03-15
Abstract: An auxiliary device for use when changing shaft seal parts (41%, 46%) in the housing of a machine, the seal parts being situated between a vertical rotatable shaft (8_) and an end wall (300) in the housing, the shaft (8_) extending into the end wall (300) through a cover (400) provided with a central hole. The other end of the shaft extends as far as internal machine parts. The auxiliary device has at least one screening device (110) arranged around the shaft. This is set up in such a way that, together with the rim (301) of the opening in the end wall it can define a small space (110a) extending around the shaft for the shaft seal parts (41%, 46%) before the exchange of the shaft seal parts (41%, 46%) but after the removal of the cover (400). This space (110a) is completely separated from the interior of the housing and free towards the opening (301) in the end wall in which the cover (400) was seated. This ensures that the auxiliary device is relatively simple and, in the event of the shaft seal parts failing or breaking, that the fitter has plenty of space for the work involved in the exchange of these shaft seal parts and that the risk of losing a tool in the housing is simultaneously eliminated. <IMAGE>
